Yes, it's pretty horrible. I'm moving back to Android so that I can use it with my Windows Notebook instead of an iPhone with my iMac. Can't really go back to iPhoto. And iPhone + Windows is a horrible workflow. The system won't allow you to set iPhoto as the default Photo Library in OS X and Photos pops up overtime you want to import somethings. The Workflow is horrible without support for external editors, and any 1080p video I drag out of Photos to the Desktop/a folder in finder gets downscaled to 720 - every single time (I have to redownload all of them from iCloud.com to get the originals... great user experience...).
Honestly if I had known this I would never have taken the Yosemite update that came with Photos. I'd have stayed on that version indefinitely. It was not worth the headache.
